"Force" calls to go through using arduino?

Projects General Guidance
1

I need a way to make phone calls from my cellphone go through on a very jumbled and weak signal network.
For now, putting aside whether or not this is legal, I simply would like to know if it is even possible to "force" a signal to go through a cell network without using some military hardware or something that I would not be able to get my hands on.
I live in an area that is both far from any cell tower and where there are so many other signals that interfere with the cellphone's signal. I'm not talking about texting/sms, or 3g/4g/5g data signals, I am simply talking about the voice signals being able to get through.
About 80% of the calls I make do not go through and don't ring on the other end, and I only get a text saying that "You missed a call from xxx-xxx-xxxx at xx:xx am/pm".
I am not the only one having this problem in my city, it is almost everyone who lives in my city that has this problem no matter what cellphone company/service they are using and no matter where they are in the city.
What I mean by forcing the call to go through is basically making the signal stronger so that any other signals in the area would have a much harder time interfering with my signal. For example, is it possible to amplify the signal from my phone in some way so that it would not be so easily scrambled or blocked or overridden by another signal so I can get through to the person I am trying to call?

If it is possible to do this, how can I do it? I am only wanting to use this for educational purposes to see if I am able to fix a common problem where I live and if it is possible, I will be talking to a friend of mine who works for the city and would be able to do something to fix or at least help with this problem.

And of course your 'amplified' signal would cause a great deal more interference to other users, interrupting more of their calls, so whilst you might benefit, everyone else is worse off. Nice.

What has this to do with Arduino in any case ?

Cellphone wireless operates at frequencies far beyond what Arduinos use.

Plus what @srnet has said.

The only answer to this problem is for the phone companies to erect more antennae to improve signal coverage.

Modern 'phones have "WiFi" calling. Switch that on and your cellphone calls are routed over the Internet. If you have no Internet service, then a 4G modem with external aerial will give what you are looking for. Your "WiFi" calls will then be routed via the modem, over the 4G service. You can use an omnidirectional aerial if you have a few cells around you, otherwise a directional and "MIMO" aerial will give you good performance.

For 2G (voice only) repeaters are available which in effect give you a "microcell" to connect to.
